The "$140,000 poverty line" is very silly

In a media landscape saturated with claims that the middle class is vanishing, Noah Smith delivers a necessary reality check by dismantling the viral assertion that a family of four needs $140,000 annually just to avoid poverty. This piece stands out not for its sympathy toward struggling families, but for its rigorous insistence that data integrity matters more than emotional resonance. Smith argues that while the official poverty line is indeed outdated, the proposed replacement is mathematically flawed and empirically disconnected from the lived reality of the average American household.

The Allure of a False Crisis

The article begins by contextualizing a recent wave of commentary, specifically targeting asset manager Mike Green's claim that the modern poverty threshold should be raised to $140,000. Green's argument, which gained traction in outlets like The Free Press, suggests that the original 1963 formula—which multiplied food costs by three—is obsolete because food now represents a tiny fraction of household spending. Green writes, "I realized that [the U.S. official poverty line]—created more than 60 years ago, with good intentions—was a lie…[W]hen you understand that number, you will understand the rage of Americans who have been told that their lives have been getting better when they are barely able to stay afloat."

The "$140,000 poverty line" is very silly

Smith acknowledges the emotional weight of this narrative, noting that housing, healthcare, and childcare have indeed become ruinously expensive. However, he immediately flags the logical leap: if the food share drops, the multiplier should rise, but Green's calculation ignores the fact that the composition of spending has changed fundamentally. Smith points out that the original 1963 metric was based on the inverse of food's budget share, but applying that same logic today without adjusting for what that share actually represents leads to absurdity. As Smith puts it, "If Mike is right, most Americans are poor people… The majority of American families make less than $140k a year."

This framing is effective because it forces the reader to confront the implication of Green's math: if the $140,000 threshold were real, more than half of American families would be living in destitution, lacking basic necessities. Smith challenges this by examining the actual material conditions of the median family, arguing that the claim fails the "smell test" of common experience.

If your family makes less than that, you must be poor. This post made the rounds like wildfire, and was generally well-received. It turns out that there's a much bigger market for the idea that $140,000 is poor than there is for the idea that $400,000 is middle-class.

The Data Disconnect

Smith then pivots to a granular analysis of the specific necessities Green lists: food, shelter, healthcare, and transportation. He marshals data to show that the vast majority of families possess these items, undermining the idea that they are struggling to meet a "participation ticket" for the economy. For instance, regarding food, Smith notes that average caloric consumption has risen significantly, stating, "In fact, of all the countries on the planet, only Irish people eat more calories than Americans."

He further illustrates that severe food insecurity affects only about 10% of married-couple households, a figure far lower than the 50%+ implied by Green's poverty line. On the topic of shelter, Smith highlights that floor space per capita has increased dramatically since 1960, noting that "Americans have more living space than people in almost any other country." Similarly, he points out that the uninsured rate has dropped to 8%, and over 80% of four-person households own two or more cars.

Critics might argue that owning a car or having a roof over one's head does not equate to financial security, especially when debt loads are high. However, Smith's point is specifically about the definition of poverty as a lack of basic survival necessities. He argues that the overlap between those lacking food, shelter, and healthcare is small, estimating that only about 25.5% of Americans live in "relative poverty," a figure that, while significant, is worlds away from Green's catastrophic projection.

Smith identifies a critical error in Green's methodology: the misuse of food expenditure data. Green cites a 7% food share, but Smith clarifies that this figure excludes restaurant spending, which was included in the original 1963 calculation. When corrected to include all food spending (around 12.9%), the multiplier drops significantly. Smith writes, "But here's the problem: Mike uses the wrong number for the percent of income spent on food!"

The Arithmetic of Error

The core of Smith's critique is that even if one accepts Green's flawed logic, the numbers simply don't add up. By using the correct food expenditure percentage, Smith recalculates the threshold to be around $80,000, not $140,000. Furthermore, he highlights that Green compares a family of four's needs against the median household income, which includes single-person households, rather than the median family income. "The median family income for a family of four, which is the example Mike talks about, is actually $125,700," Smith notes, pointing out that Green's baseline comparison is statistically invalid.

Smith's tone here is sharp but fair. He acknowledges Green as a friend but insists that professional rigor requires accuracy. "Before you go announcing that our poverty numbers are all a lie, you should probably check your numbers," he advises. This section serves as a reminder that while the sentiment of rising costs is real, the policy prescriptions based on faulty data can be misleading.

But a simple error made Mike's own calculation off by almost a factor of 2.

Bottom Line

Noah Smith's most compelling contribution is his refusal to let a compelling narrative override statistical reality; he demonstrates that while the cost of living has indeed surged, the claim that half of America is now "poor" is a mathematical artifact, not a reflection of material deprivation. The piece's greatest strength is its disciplined use of data to debunk a popular myth, though it perhaps underplays the psychological toll of living paycheck-to-paycheck even when basic needs are technically met. Readers should watch for how policymakers might misuse such inflated poverty figures to justify misguided interventions, rather than addressing the genuine, albeit different, crisis of affordability.

  • Poverty threshold

    The article directly critiques how the U.S. poverty line was calculated in 1963 (three times minimum food cost) and debates whether it should be updated. Understanding the history and methodology of poverty thresholds globally provides essential context for evaluating Green's argument.

  • Engel's law

    Green's entire argument rests on the principle that as income rises, the proportion spent on food decreases. This 19th-century economic observation by Ernst Engel is the theoretical foundation being applied (and arguably misapplied) to derive the $140,000 figure.

The "$140,000 poverty line" is very silly

Every year or so, there’s a new crop of articles about how you need to make $350k a year to live in New York City, or $150k is lower middle class, or you need $300k to be middle class, or why people making $400k are barely scraping by. This article is always roundly ridiculed on social media, and a few days later someone writes a post going through the numbers and debunking the whole thing. And then everyone posts the famous tweet:

There’s just something very annoying about publications that cater to upper-class audiences trying to reassure those audiences that they’re actually struggling.

In a recent post on his Substack — followed by a shorter version in The Free Press — asset manager Mike Green made a similar claim, but got much more positive attention for it. Instead of claiming that a family that makes $400,000 is middle class, he claimed that a family making less than $140,000 is poor. This is from the Free Press version:

I realized that [the U.S. official poverty line]—created more than 60 years ago, with good intentions—was a lie…“The U.S. poverty line is calculated as three times the cost of a minimum food diet in 1963, adjusted for inflation.”…[W]hen you understand that number, you will understand the rage of Americans who have been told that their lives have been getting better when they are barely able to stay afloat…

[E]verything changed between 1963 and 2024. Housing costs exploded. Healthcare became the largest household expense for many families. Employer coverage shrank while deductibles grew. Childcare became a market, and that market became ruinously expensive. College went from affordable to crippling…A second income became mandatory…But a second income meant childcare became mandatory…two cars became mandatory…In 2024, food-at-home is no longer 33 percent of household spending. For most families, it’s 5 to 7 percent. Housing now consumes 35 to 45 percent. Healthcare takes 15 to 25 percent. Childcare, for families with young children, can eat 20 to 40 percent.

If you keep [the original] logic [of the poverty threshold]—if you maintain [the] principle that poverty could be defined by the inverse of food’s budget share—but update the food share to reflect today’s reality, the multiplier is no longer three.

It becomes 16. Which means…the threshold for a family of four—the official poverty line in 2024—wouldn’t be $31,200. If the crisis threshold—the floor below which families cannot function—is ...
